Ob peb pawg ntawm Silica Fume
Feb 09, 2023
Ntau pawg ntawm silica fume
Kev siv cov micro-silica fume nyob rau hauv xyoo tas los no qhia tias kuv lub teb chaws kev tsim kho kev lag luam thiab ceramic refractory ntau lawm tau nkag mus rau high-tech lub sij hawm. Ntau qhov zoo ntawm micro-silica fume ua rau nws nrov hauv kev tsim kho kev lag luam. Microsilica fume tuaj yeem siv rau hauv cov cement, qhob, mortar, txoj kev loj, railway, high-speed rail, pem teb, choj, wharf txoj kab, fireproof board, refractory Hoobkas thiab lwm qhov chaw.
Microsilica fume tuaj yeem ua tau zoo nyob rau hauv cov cement void tom qab infiltrated rau hauv cement pob zeb, ua rau slurry ntau ntom. Tsis tas li ntawd, nws ua ke nrog dawb Ca(OH) los tsim ib qho chaw ruaj khov calcium silicate hydrate 2CaO.SiO2.H2O, lub zog hydrate gel yog siab dua li ntawm Ca(OH) muaju.
Txhawm rau siv micro-silica fume, nws yog ib qho tsim nyog yuav tsum nkag siab txog qhov ntsuas ntawm micro-silica fume.
Ua ntej: Cov ntsiab lus: Feem ntau ntawm cov silica fume tam sim no nyob rau hauv kev ua lag luam muaj 85 feem pua -97 feem pua. Cov nyhuv ntawm micro-silica fume nrog cov ntsiab lus qis tsis zoo heev. Micro-silica fume nrog cov ntsiab lus ntawm 85 feem pua -97 feem pua yog tam sim no cov khoom kub hauv khw.
Thib ob: Qhov ntom ntom: Qhov ntom ntawm micro-silica fume feem ntau yog 200. Cov khoom thauj khoom kuj yog siab, thiab feem ntau nws yog unencrypted micro-silicon fume. Lub micro-silica fume nrog qhov ntom ntom ntawm 600 yog hom hnyav-qhov hnyav, uas yooj yim rau kev thauj mus los thiab tsim nyog rau kev xa tawm.
Thib peb: Hom: Micro-silicon fume muaj peb hom: non-encrypted, re-encrypted, thiab semi-encrypted. Unencrypted micro-silica fume, vim nws lub teeb yuag, cov khoom thauj yuav siab, yog li ceev faj thaum yuav khoom, thiab xav txog nws cov nqi. Heavy-density silica fume yog tsim rau kev xa tawm thiab yooj yim rau kev thauj mus los ntev. Semi-encrypted micro-silica fume yog tus nqi-zoo ntawm thawj ob. Qhov tseeb, nws yog tib yam rau encrypt los yog tsis mus encrypt micro-silicon fume.
Plaub: fluidity: fluidity ntawm silica fume cuam tshuam nws cov nyhuv. Qhov siab dua qhov fluidity, qhov zoo dua cov nyhuv, ntawm qhov tsis sib xws, qhov qis fluidity, qhov tsis zoo.
Thib tsib: Xim: Cov xim ntawm silica fume yog xim dub, dawb, grey, tawm-dawb, cyan thiab lwm yam. Microsilica fume nrog cov ntsiab lus siab zoo zoo, thaum microsilica fume nrog cov ntsiab lus qis zoo li loj thiab ntxhib.
